Abstract: A display device includes: a display panel and a protective member disposed on the display panel. The protective member includes: a window disposed on the display panel; a protective layer disposed on the window; a first protective adhesive layer disposed between the window and the protective layer, and a second protective adhesive layer disposed between the display panel and the window. The first protective adhesive layer has a storage modulus of about 2 MPa to about 8 MPa at frequencies of about 20,000 Hz to about 100,000 Hz and a temperature of about 25° C. The second protective adhesive layer has a first loss factor of about 1.6 to about 2.5 at frequencies of about 20,000 Hz to about 100,000 Hz and a temperature of about 25° C.

Abstract: A display apparatus includes a display panel curved along a first direction and a backlight unit. The backlight unit includes a bottom chassis, light emitting diodes, reflecting members, and a reflecting sheet. The light emitting diodes include a first light emitting diode and a second light emitting diode. The second light emitting diode is spaced apart from the first light emitting diode in the first direction. A first area that a first reflecting member disposed under the first light emitting diode among the reflecting members is exposed is different from a second area that a second reflecting member disposed under the second light emitting diode among the reflecting members is exposed.

Abstract: A display apparatus includes a display panel curved along a first direction and a backlight unit providing a light to the display panel. The backlight unit includes a bottom chassis curved along the first direction and including a bottom portion configured to include first and second areas arranged in the first direction, light emitting diodes disposed on the bottom portion, and lens units covering the light emitting diodes in a one-to-one correspondence. The light emitting diodes includes a first light emitting diode in the first area and a second light emitting diode in the second area. A first lens distance between the first light emitting diode and a first lens unit covering the first light emitting diode is different from a second lens distance between the second light emitting diode and a second lens unit covering the second light emitting diode.
